How is temperature affected when? (a) the depth increases (b) the latitude increases

(I)The deeper the waters, the lower the temperatures. This is because sunlight is unable to penetrate to deeper water because it gets attenuated due to diffusion and scattering. In addition, warmer waters are less dense and stay as surface waters.

(II)Temperatures of water are lower with increasing latitude. This is because of the differential angle at which sunlight hit the earth at different latitudes. At higher latitudes, the sunlight travels through a longer atmosphere hence become  a bit attenuated before hitting the ground. In addition the surface area it ‘hits’ is larger than at lower latitudes.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
